Perhaps try to expand your movie universe and find genres you both like? There are lots of alternatives to the two you have mentioned.

There's a huge insecurity going on here and you dont know what it is. I'm guessing he's convinced himself you're going to cheat and possible also discovered something about himself he really doesn't like. It sounds like going could potentially cost you your marriage here so do consider that carefully. Maybe have a chat and get him to seek counselling in return for you delaying the trip. This place will almost certainly tell you your husband can screw himself and just go of course.

Not a rule just common sense. Some folks can't deal with their SO exes being in the picture.

You will if you ever date someone who has this particular problem it's very common and yes it is largely based on insecurity.

Hmm. I think that you have to get him to engage in a difficult conversation here and I'm afraid I don't know how you can start it. But you have to make him listen and understand that he's being very unfair in denying you personal satisfaction from your relationship. At least with the foreplay stuff you have a starting point as he already does that and should be willing to extend it for your benefit. Then take one very small step at a time into your new sexual world.

Do you not do any kind of foreplay. Maybe startvthe conversation there and see if you can do the same things to a finish?

Maybe not quite this but if he didn't tell his wife, that's all the Red flags you need.
